Abstract: Use of fused aryl compounds (I) for coloring keratin fibers, particularly human keratin fibers such as hair, is claimed. Use of fused aryl compounds of formula (A-CR1=B1) (I) for coloring keratin fibers, particularly human keratin fibers such as hair, is claimed.

Independent claims are included for: (1) a dye composition, for dyeing keratin fibers (preferably human keratin fibers such as hair), comprising (I) in a medium; (2) process for dyeing keratin fibers comprising applying the composition on the fibers, and optionally followed by rinsing; and (3) a multi-compartment device containing a first compartment containing a dye composition; and a second compartment containing one or more acidifying agents, alkalizing agents, solvents and/or zinc salts.
